This decorative film is to be bonded to a resin molded body by means of thermoforming, and comprises a sealing layer (I) that contains a polypropylene resin (A) and a layer (II) that contains a polypropylene resin (B). The polypropylene resin (A) satisfies the requirement (a1), while the polypropylene resin (B) satisfies the requirement (b1). (a1) The melt flow rate (MFR (A)) (at 230&#xb0; C. under a load of 2.16 kg) is more than 0.5 g/10 minutes. (b1) The melt flow rate (MFR (B)) (at 230&#xb0; C. under a load of 2.16 kg) and the MFR (A) satisfy relational expression (b-1). MFR (B)&#x3c;MFR (A) (b-1).
